群落遗传学假设，在一个基础物种中，个体的基因显著影响依赖的有机体的组合。为了评估这些种内遗传效应是否具有生态重要性，需要将它们对依赖的生物的影响与在相关空间尺度上经历的环境变化所造成的影响进行比较。对27株杨树的树皮附生真菌进行了研究。在一个随机的实验阵列中，在两个不同的地点生长着不同的基因，这些环境条件是收集杨树基因的来源。我们发现杨树基因变异对树皮附生植物群落组成有显著的影响，并且与试验地之间的环境变异程度相同。我们的结论是，保持基础物种的基因多样性可能是保护相关生物多样性的关键。
Community genetics hypothesizes that within a foundation species, the genotype of an individual significantly influences the assemblage of dependent organisms. To assess whether these intra-specific genetic effects are ecologically important, it is required to compare their impact on dependent organisms with that attributable to environmental variation experienced over relevant spatial scales. We assessed bark epiphytes on 27 aspen (Populus tremulaL.) genotypes grown in a randomized experimental array at two contrasting sites spanning the environmental conditions from which the aspen genotypes were collected. We found that variation in aspen genotype significantly influenced bark epiphyte community composition, and to the same degree as environmental variation between the test sites. We conclude that maintaining genotypic diversity of foundation species may be crucial for conservation of associated biodiversity.
